Congratulations!
You have made an excellent choice! The operating principle of your Heat Recovery Ventilator
or your Energy Recovery Ventilator will give you personal comfort you have never known
before.
We have prepared this User Guide especially for you. Please read it carefully to ensure you
obtain full benefit from your unit. Over the coming months, you will increasingly appreciate the
feeling of living in a more comfortable house.
Please take note that this manual uses the following symbols to emphasize particular
information:
! WARNING
Identifies an instruction which, if not followed, might cause serious
personal injuries including possibility of death.
CAUTION
Identifies an instruction which, if not followed, may severely damage the
unit and/or its components.
NOTE: Indicates supplementary information needed to fully complete an instruction.
We welcome any suggestions you may have concerning this guide and/or the unit, and we
would appreciate hearing your comments on ways to better serve you.
Please forward all correspondence to us at the address indicated on the product registration
card included with this guide.
CAUTION
Make sure at all times that the outdoor intake and exhaust hoods are free
from any snow during the winter season. It is important to check your unit
during a big snow storm, so it doesn’t draw in any snow. If this is the case,
please operate the unit in the recirculation mode, or turn it OFF for a few
hours.
Do not use your unit during construction or renovation of your house or
when sanding drywall. This type of dust may damage your system.
Since the electronic control system of the unit is incorporated with a
microprocessor, it may not operate correctly because of external noise
or very short power failure. If this happens, unplug the unit and wait
approximately 10 seconds. Then, plug the unit in again.
CAUTION
When leaving the house for a long period of time (more than two weeks), a
responsible person should regularly check if the unit operates adequately.
If the ductwork runs through an unconditioned space (e.g.: attic), the unit
must operate continuously except when performing maintenance and/
or repair. Also, the ambient temperature of the house should never drop
below 18°C (65°F). At least once a year, the unit mechanical and electronic
parts should be inspected by qualified service personnel.

REPLACEMENT PARTS AND REPAIR
In order to ensure your ventilation unit remains in good working condition, you must use
Venmar Ventilation ULC genuine replacement parts only. The Venmar Ventilation ULC
genuine replacement parts are specially designed for each unit and are manufactured
to comply with all the applicable certification standards and maintain a high standard of
safety. Any third party replacement part used may cause serious damage and drastically
reduce the performance level of your unit, which will result in premature failing. Venmar
Ventilation ULC also recommends to contact a Venmar Ventilation ULC certified service
depot for all replacement parts and repairs.

1. DEFROSTING MODE
When the outdoor temperature is below -5°C (23°F), recovery of heat in HRV units creates
frost in the core. For ERV units, when the outdoor temperature is below -10°C (14°F),
recovery of energy creates frost in the core.
To maintain its proper operation, the unit is programmed to defrost the recovery core. The
defrost frequency varies according to the outdoor temperature.
During the defrost cycle, the unit shifts to maximum speed and the dampers close.
After defrosting, the unit returns to the operating mode selected by the user.
2. CONTROLS
2.1 BOOTING SEQUENCES
BOOTING SEQUENCE (AVS E15 ECM HRV AND AVS E15 ECM ERV ONLY)
The unit booting sequence is similar to a personal computer booting sequence.
Each time the unit is plugged after being unplugged, or a power failure occurs, the unit will
perform a 30-second booting sequence before starting to operate.
During the booting sequence, the integrated control LED will light AMBER for 10 seconds.
After that, the LED will light RED for the rest of the booting sequence. During this RED light
phase, the unit is checking and resetting the motorized damper position.
Once the motorized damper position completely set, the RED light turns off and the booting
sequence is done.
NOTE: No command will be taken until the unit is fully booted.
BOOTING SEQUENCE (AVS E15 HRV AND AVS E10 HRV ONLY)
The unit booting sequence is similar to a personal computer booting sequence.
Each time the unit is plugged after being unplugged, or a power failure occurs, the unit will
perform a 30-second booting sequence before starting to operate.
During the booting sequence, the integrated control LED will light GREEN (unit set in
normal defrost) or AMBER (unit set in extended defrost) for 3 seconds, and then will shut
off for 2 seconds. After that, the LED will light RED for the rest of the booting sequence.
During this RED light phase, the unit is checking and resetting the motorized damper
position.Once the motorized damper position completely set, the RED light turns off and
the booting sequence is done.
NOTE: No command will be taken until the unit is fully booted.
